There are 2 major ways of producing it in large quantities: 1. Fractionally distilling liquid air (liquid nitrogen and oxygen is obtained) 2. Passing clean, dry air through one bed of a pair of zeolite molecular sieves, where high-purity oxygen is produced on one end and nitrogen on the other. There is a third, quite … Read more

Every metal has a different technique of extracting, but most commonly they use blast furnaces to melt metal ores and oxygen or carbon reduction reactions to extract metals. But you should check out Wikipedia to see the extraction techniques for the metals you wish to know, because as I've said before, for every metal you … Read more

Sulfur, or brimstone, as it's commonly known, has a wide range of uses: Fertilizers, gunpowder, matches, insecticides, fungicides, medicine, detergents, vulcanization of rubber, plastic (cellophane and rayon), sulfuric acid (battery acid, oil refinery) etc.

The s orbitals have a maximum number of 2 electrons, the p 6, d 10, f 14, and they go like this: 1s² | 2s² 2p⁶ | 3s² 3p⁶ | 4s² 3d¹⁰ 4p⁶ | 5s² 4d¹⁰ 5p⁶ | 6s² 4f¹⁴ 5d¹⁰ 6p⁶ | 7s² 5f¹⁴ 6d¹⁰ 7p⁶

The formula of ethanol is C₂H₅OH. Carbon (C) has 6 protons and electrons and 6 neutrons, hydrogen (H) has 1 proton and electron, and no neutrons, and oxygen has 8 protons and electrons, and 8 neutrons. Nr. Of protons = nr. Of electrons: 2x6 + 6x1 + 1x8 = 26; nr. Of neutrons : 2x6 … Read more

The Earth's crust is made up of huge pieces, called tectonic plates. These plates "float" on the molten magma under the crust. When they collide, fissures form in crust. Through these fissure the magma is pushed up by enormous pressure. When the magma comes out of the fissures it starts cooling and eventually solidifies. The … Read more

There 21 non metals: H, He, B, C, O, N, F, Ne, Si, P, Cl, Ar, As, Se, Br, Kr, Te, I, Xe, At, Rn

Some elements affect the development of the body. For example iodine affects height (higher amounts make you taller) and makes the body more resistant to radiation. In the case of food, it mostly depends on your metabolism. If you have a very fast metabolism (like me) than you could eat the whole market, you still … Read more
